Filed: 1983-03-18
Abstract: PURPOSE:To obtain an excellent thin film-like magnetic recording medium having no wrinkles, by installing a coming in side roller which runs in parallel a tape-like substrate around a can roller and, at the same time, installing a pressure roller which is located toward the coming in side roller from a point where the tape-like substrated is wound around the can roller at the time when the pressure is released. CONSTITUTION:A tape-like substrate 16 which is guided by a coming in side roller 12 and coming out side roller 13 runs along the peripheral surface of a can roller 11 as the can roller 11 rotates. The tape-like substrate 16 which is guided by the coming in side roller 12 is heated by the radiant heat of the can roller 11 which is maintained at a high temperature while the substrate 16 runs between the in-side roller 12 and can roller 11. A deformation of the tape-like substrate 16 caused by an abrupt temperature change generated when the substrate 16 contacts with the roller 11 is decreased by the preheating, and by pressing the substrate 16 against the roller 11 under this condition with the pressure roller 18.

Title: Etherification of carboxymethyl cellulose
Inventor: MUKAIYAMA HIDEAKI
IPC: C08B11/193
Filed: 1980-04-11
Abstract: PURPOSE: To shorten the etherification time and to reduce the amount of an etherifying agent, by dissolving carboxymethyl cellulose in an aqueous caustic alkali solution, mixing the solution, and then reacting the solution with an etherifying agent.  
     CONSTITUTION: A high-viscosity, highly activated, uniformly alkali-distributed mercerized carboxymethyl cellulose soft powder is obtained by dissolving carboxymethyl cellulose in an aqueous caustic alkali solution (30W70wt% concentration) and mixing the resulting solution at 10W60°C. The mercerized carboxymethyl cellulose soft powder thus produced is etherified, for example, by heating it together with an alkylating agent such as an alkyl halide or an alkyl sulfate and a solvent therefor. The treating temperature is specified at 10W60°C because below 10°C the time is prolonged whereas above 60°C the product is difficult to take the form of a soft powder and tends toward taking the form of a hard lump.

Title: Variable output type high voltage power source
Inventor: MOGAMI AKINORI
IPC: G05F1/46
Filed: 1983-03-19
Abstract: PURPOSE:To obtain a stable output voltage without losing a response in a wide range by varying the ratio of ON/OFF of a switch connected in series with a feedback resistor or an input resistor. CONSTITUTION:An operational amplifier A receives a reference voltage V3 through an input resistor R1 at an inverting input terminal. The output of the amplifier A is amplified by a high voltage generator G. A switch S is connected in series with the feedback resistor R2 of a feedback circuit.

Title: Ic mounting tissue material
Inventor: KUWASHIMA HIDEJI
IPC: H01L25/00
Filed: 1995-03-07
Abstract: PURPOSE: To make the resin thickness of an IC mounted tissue material after resin molding uniform, by making the thickness of a chip component nearly equal to that of an IC chip, and arranging the IC chip and the chip component in an inner layer. CONSTITUTION: By using silver paste, a circuit is formed in a specified part on the single surface of a PFT film. Excepting the part for mounting an IC chip and a chip capacitor, resin composition is spread on the PET film and turned into a semicured state by heating and drying. The IC chip and the chip capacitor are mounted in the face-down manner and connected. In this case, in order to prevent the increase of the total thickness, the thicknesses of the IC chip and the chip capacitor are preferably at most 300μm, and the thickness difference is set at most 29μm. Thereby the thickness of an obtained IC mounted tissue material after resin molding is made uniform, and unevenness is not generated on the surface by cooling after hardening or heat molding, so that printing properties are improved.

Title: Dc amplifier
Inventor: SAKAI SATORU
IPC: H03F1/30
Filed: 1987-03-02
Abstract: PURPOSE:To obtain a DC amplifier stable against temperature change with simple circuit constitution by constituting a level shift circuit by a grounded base transistor (TR) using an analog output current of a D/A converter as a current source. CONSTITUTION:A grounded base TR 12 using an analog output current I0 of a D/A converter 1 and a grounded base TR 14 are connected in cascade to constitute a level shift circuit 30 thereby allowing an emitter current of the TR 12 independent on the output current I0 of the D/A converter 1. Thus, the temperature compensation of the base-emitter voltage giving the largest effect onto the temperature drift among TR parameters changed by temperature is not required. Moreover, since no emitter current change is caused due to the temperature characteristic of the DC current amplification factor, the level shift circuit very stable against temperature change is realized.
